 - `EventRegistrationServices::ProcessConfirmation` — Registration confirmation flow
 - `RegistrantCeForm` — The CE-specific view over the inline form the **CE callout** carries (built on the generic callout→form mechanism: `RegistrationTicketCallout#forms` + `CalloutFormSubmission`; the CE callout carries a single form, read as `forms.first`). Adds the two things CE needs: the post-training form only surfaces once `EventRegistration#ce_signouts_complete?` (event ended + no open attendance entry), and completing it — read-time `complete?`, every required field answered — is a prerequisite for the CE certificate (`EventRegistration#ce_form_requirement_met?` gates `ContinuingEducationRegistration#certificate_available?`). Read by the CE callout page (which links to the generic `registration/:slug/forms/:callout_id` form page, gated so the CE callout's form opens only after sign-outs via `CalloutsController#ce_form_locked?`) and by `BuiltinCalloutCards#ce_form_pending?` for the CE card's "Complete your form" nudge
 - `EventRegistrationServices::CalloutFormSubmission` — Records a registrant's answers to one of the forms a registration-ticket callout delivers inline (`call(registration:, callout:, form:, form_params:, clarity_params:)`, returns the service instance with `#submission`/`#profile_changes`). Find-or-creates one `FormSubmission` per `(registrant, form, event)` carrying the form's own role — a re-submit edits the answers in place via `FormSubmission#persist_answer`. That a callout collected it is recorded separately in `FormSubmission#metadata` (`collected_via: "callout"`, `collected_via_callout_id`) via `#record_callout_collection!` — the flag (`#collected_via_callout?`), not the role, tells a callout-collected submission apart. There is no survey-role flag — the extra side effects self-gate on the form's own fields, so they no-op on a form that doesn't ask those questions: a choice field with linked `FormFieldResource`s (`FormField#per_resource?`) fans out to one answer per resource (nil `form_field`, `FormField#per_resource_question` snapshotted in `question_name_when_answered` — subtitle-led, so two fan-out questions sharing a prompt can't collide on one answer row); fields carrying the `anonymous_contributions` / `display_name_preference` identifiers write through to the `Person` via `PersonServices::SyncSharingPreferences` (the same write-through the registration form runs), exposing `#profile_changes` so the controller Ahoy-tracks real edits; and submitting any form on the **`scholarship`** callout stamps a recipient's `post_survey_completed_at`. Drives `Events::CalloutsController#callout`/`#submit_callout` (the person-first `registration/:slug/forms/:callout_id` page and its `.../:form_id` submit)
+- `TagTranslation` — Turns a legacy word for who someone serves into tags: `#resolve` answers with both the sector ids and the age-group ids a term means, since the vocabularies cross (`Elder Abuse` is a life experience that means the Elders *age range*). A tag's own name resolves only while it's **published** — a retired tag is unpublished, not deleted — but a recorded `TagAlias` may point at a retired one deliberately (FileMaker's `Poverty`). Splits a repeating field on line breaks and semicolons — **not commas**, which the archive's own wording contains — and drops a trailing parenthetical. Built once and reused (it reads the whole vocabulary up front); a term nothing answers to lands in `#unmatched` rather than a guess. Primacy is the caller's call, since it follows from the field a term sat in
+- `TagAliasSeeder` — Records what the FileMaker archive, the older registration/scholarship forms, Story Share and the portal's earlier sector list each called a tag the portal now names its own way (**ADR-0007**) as `TagAlias` rows, so the translation is data an admin can extend and a record of what a tag used to be called. Terms AWBW decided are recorded as-is; semantic reads of the archive's hand-typed free text are marked **`proposed`** for a pass with staff (they still resolve, so no import waits on it), and text naming an organization or a facilitator's own circumstances is left alone. Idempotent on (term, tag) and never touches a term added by hand; a term whose tag isn't published is reported, not created. Shared with `data:seed_tag_aliases`
 - `SurveyFormSeeder` — Creates the four standalone survey template forms from the form-builder presets (the Day 1 / Day 2 evaluations, the overall post-event survey, and the scholarship recipients survey), idempotent on form name and returning the names created. `#link_fanout_resources` then links each fan-out question to its training-topic `Resource`s by title (skipping any that aren't present). Shared by `db/seeds.rb` and the `data:seed_survey_forms` task so prod can create them without the full seed
 - `CloseProgramFormSeeder` — Creates the standalone "Close Program" agreement form (role `close_program`, sections `person_identifier` + `close_program`) from the form-builder presets, idempotent on form name, returning the name created (or nil). Built as an unpublished template for staff to slug + publish. Shared by `db/seeds.rb` and the `data:seed_close_program_form` task
 - `EventRegistrationServices::PublicRegistration` — Public registration handling. An affirmative `communication_consent` answer captures a News (mailing-list) `TopicSubscription` via `NewsSubscriptionCapture`, sourced to the event. A resubmission matched to an active registration sends the registrant and admins DUPLICATE emails (`event_registration_duplicate` / `event_registration_duplicate_fyi`)

+# ADR-0007 — Translating legacy sector and age-group words into the portal's tags
+
+- **Status:** Accepted
+- **Date:** 2026-10-14
+
+## Context
+
+Four systems asked people who they serve, each with its own word list:
+
+| Source | Fields |
+|---|---|
+| FileMaker (`fm_rolodexes`) | `PrimaryServiceArea`, `OtherServiceArea`, `Settings`, `LifeExperiences`, `PrimaryAgeGroup` |
+| Collab / training registration / scholarship forms | the same four, with longer prose labels |
+| Story Share | Categories, Windows Audience, Age Range |
+| The portal, before the 2026 consolidation | its own earlier sector names |
+
+The portal now carries one canonical vocabulary — `Sector::SECTOR_TYPES`, the `AgeRange`
+categories (Children, Teens, Adults, Elders), and the `StoryPopulation` categories (Self,
+Colleagues, Community, Families). The renames, merges and additions that produced it are
+already done; `db/seeds.rb` reconciles all three lists.
+
+What was never written down is how a *legacy input* becomes one of those tags. Every
+importer and backfill has to answer that per value — `PersonServices::ImportFromRolodex`
+first — and each would otherwise invent its own guesswork. This records the answer.
+
+## Decision
+
+Translation is by lookup table, not by string similarity. A value that isn't in a table is
+**reported, never guessed**.
+
+### Reading a source value
+
+- Compare case-insensitively, ignoring surrounding whitespace. Most of the archive's
+  long tail is case variants ("Domestic violence" alongside "Domestic Violence"), so this
+  alone collapses it.
+- One field may list several areas: split on **line breaks and semicolons**, then translate
+  each piece. **Not on commas** — the wording itself contains them, inside parentheticals
+  like "Community violence (gang violence, mass shootings, police violence, etc.)".
+- Drop a trailing parenthetical when the term alone resolves, so the forms' clarifying
+  tails ("Grief/loss (including COVID-related)") need no separate entry.
+- Many source values mapping to one tag is normal. Only `C & T` maps to two tags.
+- The portal spelling wins where the spreadsheet differs: **`Systems/Policy Change`** (the
+  sheet's "Sytems" is a typo).
+- `Other` is a form-only catch-all. It is never a translation target.
+
+### FileMaker `PrimaryServiceArea` → sector
+
+| FileMaker | Sector |
+|---|---|
+| Community Oppression/Violence | Community Violence |
+| Criminal/Legal | Court/Legal System |
+| Disability Services | Disability Services |
+| Domestic Violence | Domestic Violence |
+| Foster Care | Foster Care/Adoption |
+| Homelessness | Homelessness |
+| Human Trafficking | Human Trafficking |
+| Immigration | Immigration |
+| Incarceration | Incarceration |
+| Indigenous/Tribal Nation | Indigenous/Tribal Nation |
+| LGBTQIA+ | LGBTQIA+ |
+| Mental Health | Mental Health |
+| Reproductive Services | Reproductive Services |
+| Restorative/Transformative Justice | Restorative/Transformative Justice |
+| Sexual Assault | Sexual Assault |
+| Student Services | Education |
+| Substance Abuse | Substance Use/Recovery |
+
+### FileMaker `Settings` → sector
+
+| FileMaker | Sector |
+|---|---|
+| Clinical Setting | Mental Health |
+| Educational Setting | Education |
+| Faith-Based Setting | Religious/Faith-Based |
+| Hospitals | Health/Medical |
+| Law Enforcement/Court | Court/Legal System |
+| Prisons/Jails | Incarceration |
+| Private Practice | Private Practice/Sole Proprietor |
+| With Staff | Staff/Organizational Development |
+
+**Dropped, not mapped:** Community-Based, Events and Conferences, Home Visits, Outreach
+Program, Residential Program, Virtually. These say *where or how* a facilitator works, not
+who they serve — they aren't sectors and have no portal home.
+
+### FileMaker `LifeExperiences` → sector
+
+| FileMaker | Sector |
+|---|---|
+| Child Abuse/Neglect | Child Abuse/Neglect |
+| Climate/Environmental Trauma | Climate/Environmental |
+| Community Violence | Community Violence |
+| Domestic Violence | Domestic Violence |
+| Foster Care | Foster Care/Adoption |
+| Grief/Loss | Grief/Loss |
+| Homelessness | Homelessness |
+| Human Trafficking | Human Trafficking |
+| Illness | Health/Medical |
+| Immigration | Immigration |
+| Incarceration | Incarceration |
+| Mental Health Needs | Mental Health |
+| Military/Veteran | Military/Veterans |
+| Oppression Against LGBTQIA+ | LGBTQIA+ |
+| Pandemic-Related Stress | Health/Medical |
+| People Who Do Harm/Batterers | Batterers Intervention |
+| Racism and Marginalization | Racial/Social Justice |
+| Religious Trauma | Religious/Faith-Based |
+| Restorative/Transformative Justice | Restorative/Transformative Justice |
+| Secondary/Vicarious Trauma | Staff/Organizational Development |
+| Sexual Assault | Sexual Assault |
+| Student-Related Stress | Education |
+| Substance Abuse | Substance Use/Recovery |
+| Suicidality | Mental Health |
+| Victims of Crime | Court/Legal System |
+
+**No sector yet:** Elder Abuse, People Who Have Experienced War, Poverty. Left unmapped on
+purpose — each needs a sector added before it can be translated, and inventing a near-miss
+would bury the gap. An importer reports them.
+
+### Cells naming more than one sector
+
+Hand-typed answers that name several sectors resolve to all of them — the same one-to-many
+shape as `C & T`. Recorded only where every concept in the cell is itself a decided term:
+`Domestic Violence & Homelessness` · `Sexual Assault & Domestic Violence` ·
+`Domestic Violence, Sexual Assault` · `Domestic Violence and Sexual Assault survivors` ·
+`Domestic and Sexual Violence Families` · `Sexual and Domestic Violence Agency` ·
+`DV/SA/other related crimes` · `Dual Agency Domestic violence/Sexual assault/ Human
+trafficking` · `Immigration, Health, Prevention of Violence and Education` ·
+`Addiction, Native Americans, mental health and addiction` · `Education, SEL needs` ·
+`Hospice, end of life, bereavement`.
+
+### Terms that cross vocabularies
+
+Two of the archive's *sector* fields carry terms that say which **ages** someone serves, so
+they resolve to an age range rather than a sector:
+
+| Source value | Portal tag |
+|---|---|
+| `Elder Abuse` (LifeExperiences) | AgeRange **Elders** |
+| `Children's Services` (PrimaryServiceArea) | AgeRange **Children** |
+
+Whether the tag lands as the **primary** or an **additional** one follows from the field the
+term sat in, not from the term: `PrimaryServiceArea` and `PrimaryAgeGroup` are the primary
+answers, `OtherServiceArea`, `Settings` and `LifeExperiences` the additional ones. So
+`Children's Services` makes Children the primary age range, and `Elder Abuse` adds Elders
+alongside whatever the primary already is.
+
+### Reads of the free text, pending staff validation
+
+The archive's hand-typed cells are mostly a venue, a programme name or a sentence about the
+work. Where the meaning is plain — `Immigration Clinic`, `Grief support group`,
+`Inpatient Psychiatric Hopital`, `Supervised visitation sessions for foster youth…` — the
+term is recorded as **proposed**: it resolves, so an import doesn't lose it, and
+`TagAlias.proposed` is the list to walk with staff term by term. About 90 terms, each worth
+one or two archive rows.
+
+**What is deliberately not read:** anything naming an organization, a place that identifies
+one, or a facilitator's own circumstances. That text is personal and belongs in the archive,
+not copied into a catalogue — which leaves 23 terms, 23 mentions, unresolved for good.
+
+### Answers that name nothing
+
+Alongside the dropped Settings, these are recorded as naming nothing on purpose: `Other` ·
+`Did not specify` · `n/a` · `none` · `something` · `unsure` · `Everyone` · `Technology` ·
+and the delivery modes `In person` · `In visits` · `virtually & in-person` · `At office` ·
+`Office space.` · `Residential` · `On-Call/Crisis` · `Support groups`. None of them says
+who a facilitator serves, so leaving them in the undecided queue would only bury the terms
+that do.
+
+**`People Who Have Experienced War` (97) joins them by decision, not by shape.** It names a
+real experience, and Community Violence was the fallback if it had to go somewhere — but
+AWBW chose to leave it untagged rather than file it under a sector it doesn't mean.
+
+### Story Share categories → sector
+
+| Story Share | Sector |
+|---|---|

+
+### Age groups
+
+| Source value | Portal tag |
+|---|---|
+| FileMaker `Children`; Story Share `3-5`, `6-12`, `Children` | AgeRange **Children** (0-12) |
+| FileMaker `Teens`; Story Share `13-17` | AgeRange **Teens** (13-17) |
+| FileMaker `Adults`; Story Share `18+`, `Adult` | AgeRange **Adults** (18+) |
+| FileMaker `Elders` | AgeRange **Elders** (65+) |
+| FileMaker `C & T` | AgeRange **Children** *and* **Teens** |
+| FileMaker `Families` | AgeRange **Children**, **Teens**, **Adults** *and* **Elders** — serving families is serving every age |
+| Story Share `Family windows` | StoryPopulation **Families** (a story can carry a population; a person can't) |
+| Story Share `Mixed-age groups`, `Combined` | nothing — says the group was mixed, not which ages |
+
+`3-5` and `6-12` were folded into `Children` in the portal, and the `StoryPopulation`
+twins carry a trailing underscore so the clean age names stay free (see `db/seeds.rb`).
+
+## How it's stored
+
+**`TagAlias` rows, not a constant.** Each row names one legacy term, the tag it resolves
+to (polymorphic — a `Sector` or an `AgeRange` `Category`), and the system the term came
+from. `TagTranslation` reads a tag's own name first, then the aliases.
+
+- **A tag resolves by name only while it's published.** A retired tag is unpublished rather
+  than deleted so its old taggings survive, and matching one by name would hand it to
+  hundreds of new records by accident. **A recorded alias may point at a retired tag** —
+  that's someone deciding the term means that tag, which is the opposite of an accident.
+  `Poverty` is exactly that case: the sector is retired, 634 archive rows name it, and the
+  alias sends them to the tag that already carries its older taggings.
+
+- **A term can name two tags**, so a row per pair and a list on the way out (`C & T`).
+- **Unique on (term, tag)**, with the column's case-insensitive collation, so one spelling
+  can't be recorded twice for the same tag.
+- **An admin can add a term** as it turns up, without a deploy — which matters, because the
+  archive's free-text tail keeps producing new ones.
+- **`created_by` and `created_at`** make it the record of who decided a term meant a tag
+  and when. The renames and merges already ran, so the old names are gone from the data;
+  these rows are what's left of them.
+- **A term can be recorded as naming nothing on purpose** (`ignored`). That's how the
+  dropped Settings and `Other` stay out of the queue of terms still needing a decision —
+  without it, ~2,800 mentions of "Virtually", "Outreach Program" and the like would bury
+  the handful that genuinely need one.
+- `TagAliasSeeder` (and `data:seed_tag_aliases`) records the tables above, idempotently,
+  and never touches a term an admin added.
+
+The tables stay here as the readable source; the rows are the machine-readable copy.
+
+## What the archive actually holds
+
+Counted across `fm_rolodexes` (October 2026): `LifeExperiences` 55 distinct values /
+21,857 mentions · `Settings` 161 / 6,082 · `PrimaryAgeGroup` 11 / 2,356 ·
+`PrimaryServiceArea` 29 / 2,354 · `OtherServiceArea` 73 / 75.
+
+- **The canonical words dominate.** The documented vocabulary covers nearly every mention;
+  134 of the 161 `Settings` values occur exactly once.
+- **`OtherServiceArea` is free text**, not a picker: 72 of its 73 values occur once, across
+  75 rows in all. Not worth translating — it goes to the unmatched report.
+- **`Other`** appears as a stored value (90 `PrimaryServiceArea`, 60 `LifeExperiences`).
+  It is recorded as ignored rather than translated: `Sector::OTHER_SECTOR_NAME` is offered
+  for additional sectors but never as a primary, so an import can't honour it as one, and
+  "they picked Other" says nothing a tag could carry.
+- **Still needing a decision** — 23 terms, one mention each, every one naming an
+  organization, a place that identifies one, or a facilitator's own circumstances. They stay
+  in the archive and show up in the unmatched report; nothing is copied out of them.
+- **The proposed reads need a pass with staff** before the real import run. They resolve
+  meanwhile, so the work isn't blocked, and a wrong one is a row to delete rather than a
+  deploy.
+- **Coverage.** 17,734 of the archive's 17,757 mentions are translated, deliberately
+  untranslated, or proposed.
+- **Seen in the data, no mapping decided:** Children's Services, Intellectual Disabilities,
+  Maternal wellness and postpartum support, Political Asylum, Survivors with Disabilities,
+  Arts Education & Community Art Making, and the rest of the one-off free text. Deliberately
+  unseeded — each is a judgment call for AWBW, and the unmatched report is the queue.
+
+## Consequences
+
+- **Populations are not age ranges.** `AgeGroupTaggable` only tags `AgeRange` categories, so
+  a person has no population tag to carry `Families`. Rather than drop it, a person whose
+  FileMaker age group is `Families` is tagged with every age range — which is what serving
+  families means. A story keeps its `StoryPopulation` tag.
+- **One source value can produce several tags** (`C & T`, `Families`, the compound cells),
+  so a translator returns a list, not a value — and across both vocabularies, since a sector
+  field can carry an age term.
+- **Unmapped values need a report, not a fallback.** `PersonServices::ImportFromRolodex`
+  counts them in `#unmatched_tags` and the rake task prints them ranked; its name matching
+  alone resolves only the values that already read as a sector name.
+- **The translation is data, so it can retire.** Once the imports and backfills are done,
+  the rows stay as the history of what a tag used to be called — and can be dropped without
+  touching code if that history stops being useful.
